F i g. lis a section taken through an outlet means ot the invention and substantially on the line 4-4 of Fig. 3.

The form of the invention Vshown in the drawings consists of a shell 11 having a cylindrical. wall 12 and a fiat bottom 13. EX- tending upwardly from the bottom 13 inside the cylindrical wall 12 is a plurality of concentric cylindrical Walls 14., 15 and 16 which divide the shell 11 into a plurality of collection chambers 19, 20 and 21. It should be noted in Fig. 1 that upper ends 23 of the walls 14, 15 and 1G do not extend to the top o1 the shell 11.

Situated inside the shell 11 is a septum member 25 which is provided with a cylindrical tlange 26 which rests upon a flange 27 formed at the upper outer part of the cylindrical wall V12 of the shell 11. The septum member 25 provides a series of concentric cylindrical septums 29, 30 and 3l. its shown best in F ig. 1, the septums 29, 30

` anc 31 are substantially V shape and are connected together at their upper ends. The septum member 25 is also provided with an inner cylindrical flange 33 which rests on a cylindrical flange 3l formed at the upper end of the cylindrical wall 1G. The septums 29, 30 and 3l respectively extend into the collection chambers 19, 2O and 2l respec` tively. The lower ends oi' these V-shaped septums extend very close to the bottoms of the collection chambers.

The upper end of theshell 11 is closed by a cover 3S which rests in engagement with the cylindrical iiange 26 of the septum member 25. rlllie cover 38 extends entirely over vthe shell 11 and also over the septum member 25. The upper end or' the cylindrical wall 1G is closed by a plate l() which rests on the inner cylindrical flange 33 of the septum member 25. Extending downwardly lfrom the cover 38 is a pluralitv ot battles l-l, 42 and 13, these. batlies extending into a space del 'formed between the cover 38 and the septum member 25. The cylindrical baliies 11, and i3 respectively extend 'down between the legs of the V-shaped septums 29, 3() and 3l respectively, and the lower ends thereof are positioned very near to the bottoms ot these V-shaped septums. The septums 29, 30 and 31 are corrugated as shown in Fig. 1 and in Fig. 3. The purpose of this corrugation is to provide a very eX- tensive contact surface. Secured to. the lower ends of each of the septums 29, 30 and 3l and in each of the collection chambers is a conical screen 46. The conical screens 4.6 are formed ot plates which have openings 47 punched therein, these openings being either cylindrical or in the form of slots, as desired. Each of the collection chambers 19, 20 and 21 is provided with an outlet pipe 50; each of said outlet pipes 50 being provided with a valve 51.

Referring to Fig. f1, the outlet pipes extend through the bottom 13 ot' the shell 11 and the inner end of each of the outlet pipes 50 is provided with an inverted U-ffhaped portion 53. The end 54 of the U-shaped portion 53 is positioned directly adjacent to the bottom 13 so that it withdraws liquid from the bottom ot the collection chamber in which it is placed. The upper part ot each of the ileshaped portions 53 is provided with a pressure reliet port 55. Each ot the collection chambers 19, 2O and 21 is provided with a drain pet-cock 5T. Connected to the up per part of the annular collection chamber 1.9 is an inlet pipe 55 having a valve 5G. Vapor passes into the collection chamber 19, filling it, and passes down to the lower end thereof, being guided by the outer leg of the septum 29. The vapor must pass through the screen 47 so that it may pass upwardly through the other side of the chamber 19 and into the next collection chamber 20. It should be noted that the collec-tion chambers i9, 2() and 21 are all connected together at their upper ends, since the upper ends of the cylindrical walls 14 and 15 do not extend entirely to the upper ends of the septums Q9, 30 and 31. The vapor passes from the inner collection chambers through openings 57 formed at the upper end of the cylindrical wall 16 into a space 58. An outlet pipe 59 is connected to the space 5S and any remaining vapor may be conducted from the apparatus `through this pipe 59, this pipe 59 being 'provided with a valve GO. A treating medium is introduced into the space le by means of a pipe 62 having a valve 6B. This pipe'62 connects to the space del, preferably at the center thereof, and inside the cylindrical battle 413. The treating medium flows as indicated by arrows G5, down along the inner leg of the septum 81, around the baffle 43 and up along the other leg` of the septum 31, and passes above the upper ends of the septums 30 and 31 through a space 66 provided between these septums and the cover'38. The treating' medium thon passes around the ne'Xt baille l2 through a space G7, around the baille 41, and is conducted from the apparatus through a pipe G8 having a valve 69.

The operation of my invention when used as a 'deph'legmator is as follows:

The cooling 'medium which maybe water, as generally lused, is passed through the apparatus as indicated by the arrow 65, passing around the baffle plates and thereby being guided into Contact with the walls of the septums 29, 3() and 31. The vapors to be dephlegmated pass into the apparatus through the vpipe 55 and are directed as indicated by the arrows 56. More specilically, however, the vapors pass downward in the collection chamber 19 and are brought into contact with. the outer leg of the septum 29. For th-e purpose of dephlegmating the vapors condeiried by this Contact of the vapor l'mixture with the septums a body of absorbing liquid as indicated at in Fig. 3 is kept in each of the collection chambers. The vapor therefore is forced through the body of liquid 70 in the collection chamber 19,'passing through the screen 4:6 thereof. The Vvapor at vthis time has a portion of the higher boiling point vapors condensed therefrom. The remaining Vvapors pass up around the upper end ofthe cylindrical wall Minto the next collection chamber Q0, where it is directed downward lthrough the body of liquid 7() therein, and passes up around the cylindrical wall 15 into the collection chamber 21. The vapor is guided through the collection chamber 21 in the same manner as it is inthe collection chambers 19 and 20, being forced through a body of liquid TO therein, then passing upward and through the openings 57 into the space 58, whereupon it is drawn from the apparatus Vthrough the pipe 59. By providing three collection chambers it is possible to separately collect condensates o f different boiling points. The boiling` point of 'the condensates col lected, of course, depends upon the temperature in each of the collection chambers. Therefore, by controlling the temperatures therein it is possible to control the boiling points of the oil. This may be done by special control appartus in each of the collection chambers. It also may be 'done by regulating the flow of the treating medium through the apparatus. A great portion of the va aors are condensed when they pass through the apparatus, only a portion thereof (the low boili'ng'point vapors) pass from the apparatus through the pipe 59. The screens i6 assist in breaking up the vapors and bringing them into intimate contact with the bodies of'liquid 70.

One feature of the invention is the provision of a septum member having a plurality of septums which provide extensive contact surfaces. This vfeature is brought to pass by corrugating the septums. Another feature of the invention resides in the novel means of outlet arrangement as shown in Fig. 4;. It 'will be seen that the inner ends of the inverted U-shaped portions 53 connect to the chambers very close to the bottom 13. Therefore, any liquid which passes therefrom will be withdrawn from the bottom of the chambers. This is very desirable since the vapors generally vhave some steamI content which, when condensed, form water which collects in the bottoms of the chambers. l,Vater is not an eective absorbingagent and it is therefore desirable to withdraw it from the chambers as soon as collected. My invention acconr pl-ishes this, since it connects to the chambers `directly at the bottoms thereof. The level of theliquid is maintained so that the screens LG are always submerged, 'the vlevel of the liquid in each of the collection chambers being controlled by the 'upper portions of the U-shaped portions 53 of the outlet pipes 50.

The pressure relief ports 55 are provided so that any excessive 'pressure in any of the collection chambers `may be relieved. If these ports 55 are not provided, an excess of pressure vwould force the levels 'of the liquid downfbelow the upper parts Vof the screens 4:6 andfwould allow the yvapor to pass therethrough without bubbling through the llt) lit)

bodies of liquid. This would cut down the efficiency of the apparatus, since there would be no absorbing action on the vapors.

Another feature ofthe invention is that it is simple in construction. The apparatus consists of three main parts; one being the shell 11 having the cylindrical walls 14, 15 and 16; another part being the septum member 25; and the third being the cover 38 having the cylindrical baflies 41, 42 and 43. These parts may be readily assembled and disassembled for the purpose of repair and inspection, or for cleaning the apparatus. Under some circumstances it may be desirable to reverse the flow of the treating medium or the vapor, either singly or together, but this comes within the scope of my invention, which should be construed wholly by the following claims.

I claim as my invention:

1. In an oil vapor condensing and rectifving device, the combination of a series of collection chambers each having an inlet and an outlet near the top thereof; a hollow partition member in each chamber through which cooling fluid is circulated; perforated member depending from the bottom of said hollow partition; and an inverted U-shaped out-let pipe disposed in each chamber, said pipe extending upwardly to substantially the same level as the bottom of the hollow partition, with its inner end disposed near the bottom of the chamber, and an opening in the bend thereof whereby the condensate while being drawn off from near the bottom of the compartment is maintained at a constant level, and is rectified as to boiling point by the hot vapor mixture bubbling through the submerged perforated member.
